Lucy Humphreys, who was waiting to get her train, said: “I heard a huge explosion which shook the floor, a bit of smoke from under the train came out and a bit of debris flew from platform 2 where the train was over to our platform track (platform 8) and just a load of British Rail Police were running about.

“I was waiting on platform 8 at the time and unfortunately just got on my train.”

Adam Hodgson, who commented on the Get Surrey Facebook page said that he was on platforms 5 and 6 and that part of the engine cowling blew off of the train on platform 2.

Mr Hodgson added: "One piece was sent across the station and landed by platform 8."
